Question

我试图通过UIActivityViewController将视频发布到Facebook，vimeo等等。我使用的是iOS7。我听说它可能在iOS7中出现但由于某些原因我无法让它工作。

我的代码是：

NSString *shareString = @"My Personal Flick";
    NSURL *url = _URL;
    AVURLAsset *anAsset = [[AVURLAsset alloc] initWithURL:url options:nil];

NSArray *activityItems = [NSArray arrayWithObjects:shareString, anAsset, nil];

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

[self presentViewController:activityViewController animated:YES completion:nil];

有人可以向我解释我哪里出错吗？

只是为了理解我有一个打开UIImagePickerViewController的按钮，我可以选择一个视频而不是将视频保存为_URL - 这是我从中获取_URL。

------CODE FOR CREATING _URL OF VIDEO FILE-----------
- (IBAction)chooseImage:(id)sender {
    NSLog(@"Chose Image.");
    self.imagePicker = [[UIImagePickerController alloc] init];
    self.imagePicker.delegate = self;
    [self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
    _imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];

    [self presentViewController:self.imagePicker animated:YES completion:nil];

}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{


NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];

if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)
    == kCFCompareEqualTo)
{

    NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

    NSURL *_URL=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];

     NSLog(@"%@",moviePath);

    if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
        UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);

你不需要资产。电影就像任何其他文件类型的附件一样，你只需要网址。执行以下操作：

你的.h文件中的

：

@property (nonatomic, retain) NSURL *fileURL;

你的.m文件中的

：而不是

NSURL *_URL=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];

使用

self.fileURL = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];

而不是

NSURL *url = _URL;
AVURLAsset *anAsset = [[AVURLAsset alloc] initWithURL:url options:nil];
NSArray *activityItems = [NSArray arrayWithObjects:shareString, anAsset, nil];

只需使用：

NSArray *activityItems = [NSArray arrayWithObjects:shareString, self.fileURL, nil];
